Hi, all. I got sidetracked by life, and had to put my DIY screen aspirations on hold. But hopefully I can now proceed.

I looked over the TWH that I'd bought again, and feel I may have overstated the surface imperfections. Truth is, they're not that easy to pick out, short of angling a light shallow enough to rake them. Perhaps, for some reason, the lighting at Home Depot similarly exaggerated them. In any case, I'm thinking it should be fine.
The TWH's laminated Vinyl coating is fine by itself to spray S-I-L-V-E-R on, following the proper "Dusting" procedure. The first "dusted" coat acts like the primer-bonder for all subsequent coats, eliminating the need for the Kilz-2.
So, just to be absolutely clear, all I need to do is mix Delta Silver Metallic and Behr Faux Glaze at 1:20, dilute that at 4:1 with distilled water, and spray 6 to 7 duster coats of it with a Wagner Control Spray over the TWH, and I'm done?
That's eaasy!.... ("Ask me the questions, bridgekeeper, I'm not afraid."
OK, assssuming I've got that right, another question: The 1/8" TWH seems somewhat flimsy... what do people usually use for a substrate to keep it from flexing/warping/bowing on the wall?
A couple more questions:
I notice that the TWH I bought has a fair amount of sheen to it. Is that normal? Are there any downsides to this as opposed to using a surface painted with flat primer (increased risk of hotspotting, etc.)?
You'd mentioned elsewhere the possibility of adding lampblack to the mix. Did you ever try that, and what effects did it have?
